Description

Exercise device

Technical Field

The utility model relates to an exercise device. More particularly, the present invention relates to hand operated exercise devices.

Background

In gym or home use, a number of machines have been designed to strengthen and regulate leg or arm muscles. These machines benefit from being able to be placed indoors, avoid adverse weather conditions, and have a relatively small footprint, which is advantageous where space constraints prevent many people from conveniently participating in sports, running, walking, and the like.

Such machines may include treadmills, steppers, and elliptical exercise machines, which benefit users by helping them improve their cardiovascular health and/or reduce weight. These machines are considered to have a "low impact" on the human body, because the movements on the joints are relatively gentle and the impact on the body is limited in different ways depending on the type of machine used. Thus, these machines are generally considered to be the best choice for elderly people, individuals recovering from injury, or individuals with physical defects.

There are a number of elliptical exercise machines, such as U.S. patent No. 6,726,600, which describes a compact elliptical exercise device that simulates walking and jogging for arm exercises. However, such machines are not suitable for use by, for example, wheelchair users or those with little or no lower limb mobility.

Detailed Description

The exercise device 10 has two spaced apart wheels 12, 12' rotatably mounted to bases 14, 14', and each wheel is located within a housing 15, 15', respectively. The cam 16 is pivotally connected to the wheel. The other end of the cam 16 is pivotally connected to a push rod 17, the push rod 17 is pivotally connected to a handle 18, and the handle 18 is rotatably mounted in a housing 20. The housing 20 is pivotally mounted to the arm 16 such that movement of the arm upwardly or downwardly in a vertical plane by operation on the handle causes elliptical rotation of the arm relative to the wheel 12.

Disposed between the wheels 12, 12' is a seat 30 for supporting the body of a user. The chair is adjustable in its sagittal and transverse planes so that the user can adjust the height of the chair to position their hand in an optimum position relative to the body. The adjustment member for height and forward or rearward movement includes a bolt biased into an engaged configuration and a shaft having a plurality of holes, each hole shaped to receive a bolt to lock the position of the seat in a transverse or sagittal plane.

In an embodiment, the adjustment member may comprise the use of a hydraulic jack. The vertical height may be adjusted electronically or manually via a joystick.

The handle may include gripping elements to minimize sliding and lifting of the user's hand, thereby maximizing the effectiveness of the exercise.

The wheels may rotate clockwise or counterclockwise, or backward or forward, respectively, relative to the base. Generally, during the downward power stroke on the elliptical exercise machine 14, the user's hand pushes downward against the resistance of the elliptical exercise machine and returns upward with minimal or no resistance. Conversely, during the upstroke power stroke, the user's hand pushes upward and returns forward with minimal or no resistance. In the downward power stroke, the main eccentric muscles of the arm and abdomen are used, and the common muscles are relaxed. In the upstroke, concentric muscles of the arm and abdomen are used, and the metacardial muscle is relaxed.

The device also allows the eccentric and concentric muscle groups to actively participate in each of the downward power stroke and the upward power stroke. This is provided by a rotation contrast means constituted by a magnetic wheel cooperating with a pair of magnets (not shown) whose resistance to rotation of the wheel can be varied.

The handles can be oriented as desired to vary the exercise by applying different loads to different muscles, as shown in fig. 3a and 3 b.

The handle can be moved up and down in a reciprocating manner to act on the push rod 17. The position of the handle relative to the push bar is adjustable to accommodate different vertical handle positions relative to the push bar and to accommodate different heights of the user's wheels, or to focus the exercise on different muscles.

The position of the handle relative to the housing may be adjusted using a removable locking bolt that cooperates with the aperture 40.

In embodiments, the device may simply have a platform between the wheels rather than a platform between the seats to allow a wheelchair user to accommodate a wheelchair therebetween in the event that he wishes to operate the device. The wheelchair can then be locked into place. This may be beneficial to handicapped parties and other wheelchair users. Alternatively, the device may be used while standing.

Fig. 6 and 7 show an embodiment of the present invention. Exercise device 100 has a pulley system that includes a first wheel 102, a second wheel 104, and a third wheel 106 operatively connected to one another by a first belt 108 and a second belt 110.

The guide unit 218 is located at the rear of the device, the seat unit 212 is located at the front, and the crank unit 216 and the resistance unit 214 are located therebetween.

The crank unit comprises a flywheel 230 centrally mounted on a crank shaft 232, the ends of the crank shaft 232 being connected to a first crank 234 and a second crank 236, respectively.

The first and

second cranks

234, 236 are each rotatably mounted at an end of the crank axle 232 and are in phase with one another such that the respective crank

arms

240, 242 are in substantially the same position relative to one another during a rotation cycle of the crank arms.

Each crank

arm

240, 242 has pivotally mounted first and second couplers 244, 244', the first and second couplers 244, 244' having through holes with longitudinal axes perpendicular to the longitudinal axes of the

The movement of the handle may follow an elliptical path.

In use, the user adjusts the seating unit to a desired position based on height and arm length. Holding the handles, the user typically moves the handles downward or upward depending on the muscle group to be exercised. The actuating lever will rotate the crank and cause its distal end to slide in the guide 260, 260' and reciprocate back and forth while the guide itself pivots to facilitate the elliptical path followed by the handle at the other end.

When the cranks are in phase, the actuating levers 250, 250' and the handle simultaneously follow the same path.

Fig. 10 shows an embodiment 400 with a second motor that differs from the embodiments shown in fig. 8 and 9. The device 400 has handles 402, 402', 404' as smart handles that include contact points for measuring the user's heart rate while holding the handles, if desired, in addition to controls 406 on each handle. The controller 406 has a plurality of buttons to allow the user to operate the exercise machine and select exercise options, video content displayed on the screen 408, etc., wherein the screen 408 is mounted on a support arm 410, the support arm 410 being connected to a base 412 and maintaining the screen 408 at an appropriate height for viewing by the user.

Operatively connected to the rods 450, 450' is a motor 460 capable of moving the rods and thus the handle. The motor 460 has a belt 470, the belt 470 operatively connecting it to the crank shaft 472 so that by cooperating them the handle can be moved.

The motor 460 moves the handle to a position suitable for the user to start or end an exercise. For example, a user may wish to begin exercise by pushing on the handles, and the motor 460 assists in the proper position of the handles to begin exercise in this manner. Alternatively, the user may wish to start by pulling on the handle, in which case the motor 460 again assists in moving the handle to the desired position. The motor 460 is operated by the controller 406 and/or the screen 408.

The screen 408 and/or the controller 406 may be used to set predetermined starting and/or ending positions on the screen 408.

In an embodiment, the user presses a normally open switch to power the motor 460 that moves the handle.
